As i could see the website is built in wordpress, many elements are missing to meet the standard.
Home page picture is way to long and not displaying properly in mobile. And internal pages are also not designed properly.
I also tried registration form, doesn't work properly.
I can fix those all issues and make it responsive for all devices within that amount. As i am just starting to work on freelancer, i would try to provide you good value to make a good impression and get the first good review from you.
Have a great day!
Hope to work with you.
